Jasper Koers
Founder of MijnEvent and lead developer at Coding Agency. Writes the knowledge-base articles from the practice of building and running a ticketing platform.
Who writes this?
MijnEvent started at Jasper’s own obstacle run and grew, at the request of his client base, into a fair, safe and accessible ticketing platform. That dual role — organiser and builder — colours everything on this blog.
As founder and lead developer, Jasper has been in the code daily since 2010: drawing up architecture, building features and making technical choices that still hold up three years later. The articles come straight from that — no theory, but what works in the practice of ticket sales, payments and accessibility.

How to sell tickets without percentage fees or hidden costs.
Accessible ticket sales
